It's been nearly three days since a Malaysia Airlines'-branded Boeing 777-200 vanished with 239 people on board. Despite an intense, international search, authorities still have not found any wreckage of the aircraft.

There was no sign of trouble before it disappeared Friday evening, and no distress signal was sent.

Business analysts said they don't expect the Malaysian incident to have a dramatic affect on that record unless a flaw is found to have caused a problem.

"This is the best international plane ever built yet -- it's got an impeccable track record after 20 years and over 1,200 deliveries," Richard Aboulafia, vice president for analysis with the Teal Group in Virginia, told USA TODAY. "It's typically used on international routes, and it's established a new standard for international safety."

The 777 had a nearly spotless record before the crash of an Asiana Airlines flight at San Francisco International Airport in July. In January 2008, a British Airways 777 crash landed short of the runway at London's Heathrow Airport. No one was injured.
